Blending not working, possibly due to nvldumdx.dll & nvd3dumx.dll

No idea if this is the correct subforum, so feel free to move.

Ok, so I described the problem on the nvidia forum here:
https://devtalk.nvidia.com/default/topic/1038735/opengl/what-do-nvldumdx-dll-amp-nvd3dumx-dll-do-/

In a nutshell, my game doesn't blend correctly when I run
it with java. But when I capture and replay the same non-working
game with apitrace, it suddenly displays correctly!?

As far as I could see, apitrace doesn't load nvldumdx.dll ||
nvd3dumx.dll. No idea what they do though.

Also, this used to work 2 years ago, so I want to scream nvidia
driver update broke it
...

To make things even more fun, the exact same code runs on my
ati card
.
